Figure 1. The total Gini-based carbon emission footprint index. It shows the Gini decomposition results of China’s apparent province-level carbon emissions from 2000 to 2021. The horizontal axis represents the year, the left vertical axis represents the stack area plot value, and the right vertical axis represents the line plot value. The total Gini-based carbon emission footprint index can be divided into four aspects: raw coal, crude oil, natural gas, and cement. The line plot with marked points expresses the total Gini-based carbon emission footprint index. The stack area plots express the Gini-based carbon emission gap in those four sub-indices from bottom to top in an orderly fashion.
